The original plan that gives this small room its name is enhanced by the Neoclassical motifs that adorn the walls and ceiling, simulating stucco. One display case exhibits one of the most interesting pictorial groups in the Museum’s collections, painted by Nicolas Delerive, an artist of French origin who was active in Portugal and became well-known for his portrayals of society and the customs of Lisbon life in the late 18th and early 19th centuries. Made up of 14 small paintings, this series represents a variety of trades and customs: the ‘mondi nuovi’ trader, the chestnut roaster, the bottle seller, the knife grinder, the blacksmith, the locksmith, the blind beggar, the baker, the prisoners’ soup, the water carriers, the chair manufacturer, the wheelwright and, evoking the dissolution of the customs of the old regime, two scenes showing brothels with friars.

The collection of secular silverwork displayed in the other case provides an excellent sample of Portuguese Neoclassical production. Worthy of attention, among other pieces, is the almost miniature tête-à-tête tea service produced by the prolific and highly-skilled silversmith António Firmo da Costa, inspired by the Adam models from England.
